Livesync hangs when modifying App_Resources in before-prepare hook

Tell us about the problem

When using nativescript-localize with "tns run ios", it tries to sync Localizable.strings without rebuilding the app.

Which platform(s) does your issue occur on?

iOS, haven't tried on Android

Please provide the following version numbers that your issue occurs with:

• CLI: 3.3.1
• Cross-platform modules: 3.3.0
• Runtime(s): 3.3.0
• Plugin(s): nativescript-localize (2.0.5)
• iOS 11 on iPhone X emulator

Please tell us how to recreate the issue in as much detail as possible.

git clone --depth 1 --branch v2.0.5 https://github.com/lfabreges/nativescript-localize.git
cd nativescript-localize
npm install
npm run compile
cd demo
npm install
tns run ios

Then make a change in the app/i18n/en.default.js file, change "Hello World !" to "Hello" for example.

I think the problem occurs because :

• The plugin modifies Localizable.strings in the App_Resources
• Prepare is done and savePrepareInfo save the .nsprepareinfo file with a modified time greater that Localizable.strings modified time
• The watcher detects that a change has been made to the Localizable.strings and add it to the queue
• Prepared is skipped because no change is detected, appResourcesChanged is not set to true because containsNewerFiles returns false because Localizable.strings has been modified before .nsprepareinfo file is written to disk
• Localizable.strings is synced but without a rebuild and the app hangs, I need to stop tns run, remove the platforms directory and fully rebuild and resinstall the app to make it work again

I tried to hook into the process but did not find a way to fix it, I triggered a build by modifying appResourcesChanged directly into the plugin, it works but Localizable.strings is stilled synced afterwards, so it hangs again.

I'm the author of the plugin, so I can change it if needed. I definitly need some help on it.

Regards.

Reproduza o problema com os comandos de demonstração do nativescript-localize listados e, em seguida, inspecione hooks/before-prepare/nativescript-localize.js, App_Resources e o tratamento de .nsprepareinfo. Rastreie como o watcher, a decisão de prepare-skip e a sincronização de Localizable.strings interagem. O trabalho estará concluído quando alterar app/i18n/en.default.js não fizer mais o aplicativo iOS travar e o rebuild necessário ou a atualização de recursos for concluído com sucesso.
